How To Install & setup Python 3.8 Version on Windows 10

 

1- Installing Python from Python.org

Go on Python.org at the section where you can download the windows executables:

https://www.python.org/downloads/windows/

Go down in the page and download the following executable (if your computer is 64 bits):

Windows x86-64 executable installer

Double click on the executable and install it

2- Add Python 3 to the windows 10 environment variable path

I will suppose that you didn’t check the “add python to the path” checkbox when you installed it.

Let’s see now how to add this new python 3 version to the path

By default, it installs in the path:

C:\Users\cypri\AppData\Local\Programs\Python

(cypri will be replaced by your windows user name of course…)

This is not convenient, because AppData is a hidden folder and it may cause problems with some python modules such as jupyter if you leave it here

The move is to C:/

Change the name of the executable to python3.exe for convenience

Let’s now edit the environment variables to add this new python 3 to the path:

Add the 2 new variables as follow:

  • C:\Python38\
  • C:\Python38\Scripts

then click on OK

Now open the command prompt:

When you type “python3” in the cmd, you should see the Python 3 interpreter opening:

3- Upgrade pip to be able to install Python modules

If you try to run pip3 for this new python install, you will run into the following problem:

“Fatal error in launcher: Unable to create process …”

To correct that, enter:

python3 -m install --upgrade pip

Your pip will then be upgraded and you will become able to install again python modules

That’s all!

Note: Same Procedure to All New version (python3.9, Etc) or Old version (Python3.7, etc)
